Tools You'll Need:
* Jack and jack stands: Essential for safety! Never work under a car supported only by a jack.
* Wheel chocks: To prevent the car from rolling.
* Lug wrench: To remove the wheels.
* Socket wrench set: Including metric sizes.
* C-clamp or caliper compression tool: To compress the caliper piston.
* Wrench for caliper mounting bolts: Likely 13mm or 14mm.
* Wrench for brake line banjo bolt (if applicable): This may be needed depending on your brake line setup.
* Hammer and punch (optional): May be helpful if the caliper bolts are stubborn.
* Torque wrench: Crucial for properly tightening bolts to prevent damage.
* Brake cleaner: To clean brake parts.
* Grease: For caliper pins.
* New front brake pads: Get the correct ones for your Cavalier.
* New front brake rotors: Ensure they are the correct size and specifications.
* Gloves: To keep your hands clean.
* Safety glasses: To protect your eyes.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks on the rear wheels.
2. Raise and Secure the Vehicle: Jack up the front of the car and securely place it on jack stands. Make sure the jack stands are properly positioned under sturdy parts of the frame.
3. Remove the Wheels: Remove the lug nuts and carefully take off the wheels.
4. Remove the Caliper:
* Use a socket wrench to remove the caliper mounting bolts. They're usually on the back of the caliper.
* Before removing the caliper completely, use the C-clamp or caliper compression tool to push the caliper piston back into the caliper. This creates space for the new, thicker brake pads. Some brake fluid may leak out, so have a rag ready.
* Carefully hang the caliper from the suspension using a piece of wire or bungee cord to avoid putting stress on the brake line.
5. Remove the Brake Pads: The old brake pads should now be easily accessible. Remove them.
6. Remove the Rotors: Depending on your model, the rotors may simply slide off after removing the caliper and pads, or they may be held on with screws. Consult your repair manual for specific instructions.
7. Clean Everything: Thoroughly clean the caliper mounting surface, brake caliper, and hub using brake cleaner.
8. Install the New Rotors: Install the new rotors, ensuring they are properly seated.
9. Install the New Brake Pads: Slide the new brake pads into place.
10. Install the Caliper: Attach the caliper to the mounting bracket, making sure the caliper mounting bolts are tightened to the correct torque specification (consult your repair manual).
11. Install the Wheels: Carefully put the wheels back on and tighten the lug nuts.
12. Lower the Vehicle: Slowly lower the vehicle from the jack stands.
13. Final Tightening and Check: Once the car is on the ground, give the lug nuts a final tightening.
14. Pump the Brakes: Pump the brake pedal several times to build up pressure in the brake system.
15. Test Drive: Take a short test drive to ensure the brakes are working correctly.
Important Considerations:
* Brake fluid: You might need to bleed the brakes after replacing the pads and rotors if you've opened the brake system. Bleeding brakes is a more advanced procedure.
* Torque Specifications: Always refer to your vehicle's repair manual for the correct torque specifications for all bolts.
* Parts: Buy high-quality brake parts from a reputable supplier. Using cheap parts can compromise safety.
* Safety: Always prioritize safety. If you're unsure about any step, consult a professional mechanic.
This is a general guide. Always consult a repair manual specific to your 1999 Chevy Cavalier for detailed instructions and torque specifications. Failure to follow proper procedures can result in brake failure, which is extremely dangerous. If you're uncomfortable with any part of this process, seek professional assistance.
